Invariant mass spectra of τ−→h−h−h+ντ decays

Using 342 fb−1 of e+e− annihilation data collected with the BaBar detector at the SLAC PEP-II electron-positron asymmetric energy collider operating at a center-of-mass energies near 10.58 GeV, we present the preliminary measurements of the invariant mass distributions of τ−→π−π−π+ντ, τ−→K−π−π+ντ, τ−→K−π−K+ντ and τ−→K−K−K+ντ, where events with decays are excluded.
